  • Patent number: 7768402
    Abstract: A method and system for reading and identifying RFID tags of the invention is disclosed. The invention is capable of registering and storing information of a plurality of RFID tags attached to objects of the same group into a memory block of at least a specified RFID reader or RFID tag. The invention is also capable of enabling at least a specified RFID reader/tag in response to a first inquiry of an interrogator by transmitting each identification code of the plurality of RFID tags to the interrogator for acknowledgement. The method is capable of achieving the objective of reducing the overall communication time as the reader does not have to inquire one by one to the RFID tags to save the number of times of communication between the inquiry of the reader and the response of the RFID tags. In addition, the reading rate of the RFID system can be improved effectively since at least one of the RFID tags can function as a spokesman for those RFID tags hidden deeply inside a pile of the objects of the group.

  • Patent number: 7103433
    Abstract: A method for providing service for users to determine assembly match information of components is proposed. The method makes use of computer programs of a communication equipment and cooperation of a database and tag information on the components to provide inquiry judgement and match decision of components for users, thereby accomplishing realtime match inquiry of components and also avoiding erroneous manual assembly. The method not only can provide related specification information of components, but also can provide suggestion for component schemes. If the assembly match information changes, update information of the remote database can be transmitted via the communication equipment to a read/write device to update assembly match information in tags on components.
